Up to DVB-S2X-256APSK according to their data sheet. :87:
http://www.tbsiptv.com/download/tbs69…_data_sheet.pdf

I googled some reviews for the card but not able to see any. Just waiting if it is supported by CrazyScan and that it is not as buyyg as the TBS 6522 and it sisters.

Is this card using the STid135 demodulator?

**satesco** · January 12, 2019 at 1:06 PM

1.Yes,tbs6903X uses STiD135 demod.
2.It is also supported by Crazyscan.

added:Crazyscan scanned 19.2E with this card

Do you think crazyscan correctly supports this card?
Then explain, please, why the RF level, for example, at a frequency of 10980 H according to the results of a blind search is -32dBm, and the height of the transponder peak on the left scale is 45dBm (77dBm !!! more)

I'm not the right person for your question.Would it be presumptuous on my part to explain it to you,an expert in this kind of application,if crazyscan correctly support 6903X card.It's not my territory.
But if I had to give my opinion,of course as a simple user,then,metaphorically speaking,this demod is like a Formula One engine but running at the usual speed,under its capacity.That's why it's a challenge for any developer who wants to optimize his application for this type of card.
My regards

Thank you for your respond. Can you give us a screenshot of a satellite using a DVB-S2X frequency? How smooth is the scanning? Are there any repetitive crashes?

**satesco** · January 13, 2019 at 12:20 PM

Thanks KooLy I'm sorry I will not write about 6903X or 6909X yet. I'll do it when the right time comes.When? I don't know yet...

Silabs BLScan2 usual fast (65xx, 55xx), but sometimes buggy (hungup on low SR transponders).
STV091x BLScan2 very fast and precise (6983, 6903/5/8, 5927), but S2X not supported.

STiD135 is some new, FBC tuners + flexible demods + streaming engine. This very complex solution and blindscan not primary task.

Peon`s 9th PC card for his DXing. 8 of `em are TBS cards.

More details as soon as he gets a bit more familiar with the new card.

sato · January 24, 2019 at 10:17 PM

First reception shots made by TBS 6903X card.
Peon is testing and trying to do different things. There is significant need of CRazy Cat`s support for this card.

crazycat provided the Crazyscan support for the 6903X card as much as the demod allows.A solution should be found,if possible(?),for ultra fast scan for this demod.At least that's my impression since I tested this card.

Thanks for the reviews.
What is the frequency range of the card? Crazycat's streamreader can do 250MHz to about 2450MHz using a TBS6983/6903 (with changes to default .ini file)

**satesco** · January 25, 2019 at 12:40 PM

Tbs6903X-The frequency range is 250-2150 MHz,so configured in StreamReader.ini(v.1.2.4.74).

The 6903X drivers for Windows and Linux are now on the TBS site

An other monster card from TBS DVB-S/S2X ACM/VCM 256APSK

they add too a "noisy fan"

I don't know but it seem to me that it has a bad spectrum at least is better than tbs-dvbs2x-cards 's spectrum (TBS6522&TBS5521)

Can you see NO-LOCKED signals with it? like other professional-cards with Crazyscan?!

Peon · January 31, 2019 at 8:40 AM

TBS6903x does not yet have support from CrazyCat. Scans are incorrect. Compare signal levels with TBS6983, TBS6903, TBS5927.

**satesco** · January 31, 2019 at 1:56 PM

tbs6903X-scanned 8k transponder at 85.0E with Crazyscan and played with ProgDVB & DVB Dream.

Even if I read what you said right now, I assure you that tbs6903 has the support from crazycat.Even if the comparison with previous cards is justified,6903x is missing something important and not implemented by SMT,namely,ultra-fast Blindscan.Because of this blindscan function is restricted to a simple search blindscan and search is slow.That makes BLScan2 not find transponders with weak signal on search step by step.In fact,the no-locked signal doesn't even appear in the spectrum,as it was on cards mentioned by you.
So, crazycat did everything that depended on him to capitalize on the "steroids" of the card, but now the ball is the court of another player.At least I think so at the moment Otherwise Tbs6903X does everything other professional tbs cards do
I would very much like to be wrong about some statements made above.
Here's what the blindscan looks like with this card at 18.0W:
